Debian 11 “Bullseye”Will be released in 2021 but as of today we know that the theme he will use is called Homeworld. The Homeworld theme was created by Juliette Taka and is inspired by the German Bauhaus art movement, which began in the late 19th - early 20th century.
Users will see the Homeworld theme in several places when using Debian 11. One of them will be in the program installation of Debian.
Homeworld will exist like wallpaper but also in screen connection.
Following a call for new topics, a total of eighteen selections were submitted. In one poll the projects received 5.613 votes and the Homeworld theme was the top choice of users.
If you ran Debian 8 or Debian 9, you will have already come across Juliette Taka's work, since she created the issues Lines and softWaves used in these two releases.
